HEAT TREATABLE COATED ARTICLE WITH NIOBIUM ZIRCONIUM INCLUSIVE IR REFLECTING LAYER AND METHOD OF MAKING SAME

摘要

A coated article is provided so as to include a solar control coating having an infrared (IR) reflecting layer sandwiched between at least a pair of dielectric layers. The IR reflecting layer includes NbZr and/or NbZrOx in certain embodiments of this invention. The use of such materials as an IR reflecting layer(s) allows the coated article to have good corrosion resistance to alkaline solutions, good mechanical performance such as scratch resistance, and/or good color stability (i.e., a low .DELTA.E* value(s)) upon heat treatment (HT). The coated article may or may not be heat treated in different embodiments of the invention.
